Cleaning up After Ourselves

And making it work for us

Landfill biogas is a by-product of the anaerobic decomposition of biodegradable waste in landfill sites. In its original state, landfill gas typically contains 50 percent methane (CH4) with a relatively high energy content of 36 megajoules (MJ) per cubic meter of CH4.

However, methane is a potent greenhouse gas with 25 times the global warming potential of carbon dioxide (CO2). An estimated 8 percent of global methane emissions released into the atmosphere comes from landfills. If LFB is captured and used for energy production, not only are these emissions reduced but a non-conventional source of energy displaces traditional fossil fuel use.

The utilisation of landill gas for electricity generation is an established commercial activity. The days of risk assessment and uncertainty have long since passed and the technology involved may be applied with certainty.

We highlight below some of the projects we have undertaken around the world.
